Title: Terminal for electronic part for adjustment
Inventor: KITAKI ARATA
IPC: H05K3/40
Filed: 1993-12-22
Abstract: PURPOSE:To lighten the work of removal of solder and resoldering being performed each time, though the exchange work of parts occurs until the constants of parts are decided in the case of mounting electronic parts for adjustment on a printed board. CONSTITUTION:This is a terminal which has a cross-shaped cut at the head, and in the case of having inserted the lead of an electronic part into the cut, the cut is transformed, and by the spring property, it retains the lead. Since it is retained both electrically and mechanically, there is no necessity to solder the lead of a part at the time of adjustment of electricity, and the exchange of the part can also be performed merely by the insertion and the extraction of the lead to the cut of this terminal. It is possible to solder this terminal with the cut part after the constants of parts are decided, and the work at replacement of parts can be lightened.

Abstract: PURPOSE:To keep a good printing quality of a printer and to inform users whether a maintenance is required, by a method wherein a time to energize heating elements is calculated according to the measured values of resistance of heating elements, and whether the heating elements function satisfactorily is judged. CONSTITUTION:When the value of resistance of a thermal head is measured, a relay 5 is made unactuated by a control unit 1, a voltage is supplied to a partial pressure resistor Rr by a power supply 8, and the electric potential is read by an A/D converter 6 through a buffer 9. In this manner, data relating to the values of resistance per heating element digital-converted by the A/D converter 6 is stored in a memory 2 through the control unit 1. On the other hand, the control unit 1 judges whether an abnormal value exists in the values of resistance per heating element stored in the memory 2. If it is present, an abnormality indicating circuit 7 is actuated to display the presence of abnormality in a thermal head.

Title: Image carrier and image forming device
Inventor: MOTOHASHI SATORU
IPC: G03G5/05
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent an image with stripes caused by the wear of the surface of a photoreceptive drum from being generated while preventing an image flowing from occurring by setting the mean diameter of the chips of the surface of an image carrier to be equal to or under a specified value. SOLUTION: The photoreceptive drum 2 is constituted so that an aluminum- made hollow cylinder whose diameter is 24 mm is used as the substrate 2a and successively provided with an under-coating layer 2b, an electric charge generation layer 2c and an electric charge transportation layer 2d on the surface of the substrate 2a. Then, the mean diameter of the chips of the photoreceptor is set to be <=9.0 μm. Thus, the image with the stripes is prevented from being generated. Since the depth of a flaw caused at the surface layer of the drum 2 corresponding to a position where paper powder is caught by a cleaning blade is deep when the diameter of the chips is large, shaving spots are formed at a photosensitive layer and the surface roughness of the drum 2 becomes large. When the shaving amount of the photosensitive layer becomes large, the image with the stripes appears.  Besides, when the shaving amount is >=16 g per traveling distance 1.0×106 mm, the image flowing can be prevented from occurring.
